Step-by-step explanation:
Step 1- Multiply
20×0.25= 5
15×0.35= 5.25

You solve by 140-68 which equals 72
So x=72 degrees
Answer:
t≤ 9
Step-by-step explanation:
3.5+4t≤ 39.5
subtract 3.5 from each side
4t≤ 36
divide each side by 4
t≤ 9
5x+4y=8
-5x from both sides, you get 4y=-5x+8
then you divide the equation by 4.
y=-5/4x+2
10x-4y=46
-10x from both sides and you get -4y=-10x+46
divide the whole equation by -4 and you get y=5/2x + -23/2 .
